Abstract :
A new solution for analog AC to DC transfer is described. It differs from standard analog AC to DC transfers, such as time-division because it works inherently digitally. The complete schematic of the device is given, as well as an original method for theoretical and simulation analysis. The device is built and good agreement between simulation and calibration results is achieved for sinusoidal input(s). The accuracy of prototype version was better than 0.51% FS. It is shown how to build an analog divider and router using this device. Thus, this paper represents a contribution to the theory and practice of analog arithmetic operations
